How to clear your Internet Explorer cache

Sometimes when connecting to the PoliteMail Server, typically after an update to Outlook or PoliteMail, you login credentials may fail, despite being accurate.

This is typically due to an Internet Explorer cache issue. The solution is to clear your IE cache (as Outlook only utilizes IE, it doesn’t matter what browser you use, you must clear the IE cache).

1. Close Outlook and open Internet Explorer.  Using CTRL+SHIFT+DELETE will open the clear cache window immediately.

2. Click the gear button at the top right (under the red close window button)

6. Close IE and restart Outlook
